Answers
The answers for both the parts are as (a) the rate of proofreading is 7.5 pages per hour and (b) The payment received for each page is $2,.67.
What is Unitary method ?
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The pages proofread in 2 hours is 15.
The total amount received is $40.
(a) The proofreading rate can be known by dividing the total pages by total time as below,
Rate of proofreading = 15/2 = 7.5 pages per hour.
(b) As per the question the unitary method can be applied to obtain the payment for one page as follows,
Payment for proofreading 15 pages = 40
Thus, payment for proofreading one page is 40/15 = 2.67.
Hence, the proofreadingrate is 7.5 pages per hour and the average payment for each page is $2.67 respectively.

3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º
Answer: ∠a=46º.
4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º
Answer: ∠b=134º
5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º
Answer: ∠c=134º
6)∠d
112º+d=180º
d=180º-112º
d=68º
Answer: ∠d=68º
7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º
Answer: ∠e=48º
8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º
Answer: ∠f=132º

For the second one, the tenths place is the one just on the right side of the decimal. Find the number right before it. If the number is 5 or higher, then you round up. It's 5, so round up, and get rid of the 2 at the end. Since you round up to 10, not 0, you need to add a 1 to the 8. Your answer should be 78.9
